Have you considered using PDF::API2[1] for this?
It seems to me you are massaging your data from one structure
(xml::simple's hashref) into TT and then converting it into PDF. You
could skip this TT part and write it straight out. Moreover,
re-reading your previous messages, I also wonder if your trying to do
too much with your dataset. Your requirement to 'search and get
address' sounds like you need to do the kind of lookups that
databases were engineered to handle. XML (love it or hate it) is best
suited for transmitting data. You can search within it, in which case
I'd recommend XML::LibXML[2] so you can unleash find(), findvalue()
and the like, but it sounds like your over-reaching with the tools
your using.
The answer to how you can look-up the address given the student id is
really to store the data in a way you can look it up. So address will
have to have an ID and student will have to have one or more addresses
assigned to them:
'student'=>[
{
'name'=>'mikky',
'number'=>'12',
'address_id'=>'123', ***
'semester'=>{
'Number'=>'1',
'subjects'=>'7',
'rank'=>'1'
}
},
